Effect of Phosphorus Management and Drought Mitigating Strategies on Yield and Economics of Rainfed Chickpea

Abstract

A field experiment was conducted to find out the Phosphorous and drought mitigating strategies on yield and economics of Chickpea (var. RVG-202) with the different levels of Phosphorus (40, 50, 60 P2O5 kg/ha) and with the application of Drought mitigating strategies applied at pre-flowering and pod formation stage) respectively, at Crop Research Farm, Department of Agronomy, Faculty of Agriculture, SHUATS, Prayagraj, Uttar Pradesh, India. The soil of the experimental plot was sandy loam in texture, nearly neutral in soil reaction (pH 7.1), low in organic carbon (0.28%), available N (225 kg/ha), available P (19.50 kg/ha) and available K (92.00 kg/ha). The experiment was laid out in Randomized Block Design, with ten treatments and replicated thrice. Results obtained that there was a significant increase in yield attributes viz., Seed yield (2332.00 kg/ha), Straw yield (4571.33 kg/ha) and Harvest index (33.51%) were recorded with the application of P2O5 60kg/ha + 25kg ZnSO4/ha + 1%KCl +0.5%sodium selenite spray. However, Maximum Gross return (124481.70 INR/ha), net return (89064.67 INR/ha) and B: C ratio (2.51) was recorded with the application of P2O5 60 kg /ha+ 25 kg ZnSO4/ ha + 1 % KCl + 0.5 % sodium selenite spray. Therefore, it is concluded that the application of P2O5 60 kg /ha+ 25 kg ZnSO4/ ha + 1 % KCl + 0.5 % sodium selenite spray was more productive and economically feasible.
